IMPROVEMENT IN BLIND-STOPS.

Specification forming part of Letters Patent No. 174.558, dated March 7, 1876 application filed February 1, 1876.

To allwhomit may concern Be it known that i, GEORGE H. NrssEN, of New York city, county and State of New York, have invented certain Improvements in Bind-Slat Adjusters, of which the following is a specification:

The object of my invention is to prevent the noise-and rattling of Window-blind slats, and injury to them, occasioned by the action of the wind; and also to adjust the slats automatically in any desired position.

My invention consists in placing the axles ot' the slats in vindia-rubber Vor gutta-percha sockets or journals, which are inc'losed in metal rings or short tubes inserted in holes bored into the inner sides ofthe blind-frame opposite the axle ot' the slat, theindia-rubber sockets being provided With projecting faces, which press against the ends of the slats.

By this device a certain friction is obtained to the axles, and also to the ends of the slats, which friction prevents them from rattling in their sockets, and keeps them automatically in any desired position of adjustment.

But, that my invention may be fully understood, I Will describe the same in detail by aid of the accompanying drawing, which forms part ot' this specification, and represents a iront view ot a blind With part ot' the frame removed in order to better illustrate my invention.

A is the frame of the Window-blind. B are the slats. C the axles of the slats. d is a hole bored in the frame A opposite each axle c, in Which the metal ring or short tube E1 and the elastic socket or journal E are inserted, the journal E having a hole, f, in which the axle O of the slat is placed.

The elastic journals are also formed with projecting semicircular faces E2, which, When.

vrings or tubes E1, and inserted in holes d of the frame, the said journals E 'being provided with holes f for the axles of the blindslats, and with projecting faces E2, all constructed and operatin g as and for the purpose described.

This specication signed this 7th day of January, 1875.
